Uni POSCA Mop'R Marker, XXL (3-19mm), Water-Based & Multi-Surface, Red – Pack of 4

The Mop'R Marker XXL features an adaptable nib range from 3 mm to 19 mm. You can draw fine details with the thinner end and widen strokes or fill large areas by using the broader part of the nib, giving you versatility from precision outlining to bold blocks.

Yes. The ink is water-based and formulated to be non-toxic, making it suitable for general art use and safe for educational settings. Always use in a well-ventilated area and supervise younger users as needed.

It performs well on a wide range of surfaces like paper, cardboard, wood, plastic, metal, glass, and fabric. For non-porous surfaces, you may experience longer drying times or require a few extra passes for opaque coverage. Always test on a small patch first if you’re unsure about a new surface.

Shake well before use, remove the cap, and prime the nib by pressing it gently onto scrap paper until ink begins to flow. Use long, steady strokes and vary pressure to control line width. Allow quick-drying ink to set before touching or layering colors.

Cap the marker after use and store horizontally or with the nib facing slightly downward to keep ink accessible. Avoid heat sources and prolonged exposure to direct sunlight to maintain nib performance and color consistency.

Great for bold lettering, signs, murals, poster art, calligraphy practice, fabric embellishments, scrapbooking, and crafts that require strong color payoff on diverse surfaces.

The Mop'R XXL focuses on a larger nib range (3–19 mm) for bold fills and large-area work, whereas PC-5M and PC-7M offer mid-sized nibs suited for more controlled lines and detail. If you need thick, expressive strokes and fast coverage, Mop'R XXL is ideal; for precise lines and smaller lettering, PC-5M or PC-7M may be better fits. See these alternatives on Fepy:
